About certificate history for tubsd1fa69b60903a6da24ad32454b8711d1b6.zendesk.com

This page lists every X.509 (SSL/TLS) certificate ever issued for tubsd1fa69b60903a6da24ad32454b8711d1b6.zendesk.com and its subdomains, as recorded in public Certificate Transparency (CT) logs. CT logs are an immutable, append-only record of every certificate issued by participating Certificate Authorities (CAs), as required by the major browsers since 2018.

Subdomain enumeration via CT logs is one of the highest-signal techniques in reconnaissance — every time a TLS certificate is issued, all Subject Alternative Names (SANs) on that certificate become public. Internal and forgotten subdomains regularly show up here days after they're set up.

To monitor tubsd1fa69b60903a6da24ad32454b8711d1b6.zendesk.com for newly-issued certificates in real-time (useful for detecting unauthorized issuance, phishing variants, or shadow IT) add it to your watchlist (Pro plan).
